Quality code
Configuration of quality codes
The quality code (QC) provides information on the results of a tightening job. If an NOK evaluation is
output, the cause will also be listed.
By assigning the cause of NOK evaluations from tightening processes to specific quality codes, it is
possible to subdivide the results into certain areas. These can be useful e.g. when evaluating the output
tightening results.

)MF = monitoring function
There is no counter value for program 99, since it is used as a loosen program.
In addition to the quality code, the PLC OK/NOK signal must also be used for the evaluation. A monitoring
function not selected in the tightening program is regarded as OK on assignment of the quality code.
